I am trying to make a python idle using tkinter ,I am almost done but I am facing this issue:

I am using subprocess module to run the code which user has written but i am trying to use the input statement the program is crashing and I do not know why

This is the code which is running the program:-

def run():
    if file_path=="":
        save_prompt=Toplevel()
        text=Label(save_prompt,text='Please save your code!!',height=10,width=20)
        save_prompt.iconphoto(False, photo)

        text.pack()  
        return
    command=f"python {file_path}"
    process=subprocess.Popen(command,stdout=subprocess.PIPE,stderr=subprocess.PIPE,shell=True)
    output,error=process.communicate()
    
    code_output.delete("1.0",END)
